BOTTLE-FILLING MACHINE 1 Application filed J u1y 17,"1923, SeriaI'No. 652,088, and in Great Britain September. 19, man.-

f This invention relates to a bottle, filling on the base by bearings 8psee On ,machine o'i' the multiple headed rotary type and has vtor its chief object to facilitate the adj ust'm'ent of the machine to take different Llengthsot'bottles, to nable bottles to be :automatically transferred to and from hottle' rests-'x'vithout collidiuggwith any guards .that may be used, to prevent waste of liquid when bottles are not placed in position and to, providean improved form of liquid distribution valve. According to this invention the rotary filling heads are carried by a vertical member, that is arranged to be raised and lowered by suitable mechanism for adjusting the machine to take difl'erent lengths of bottles and angularly displaceable divisional bottle i :guar,ds,are used which are adapted to extend ,between the filling heads and the bottle rests and tobe moved above the level of the latter toprovidea free passage for the transference of thebottles to and from the bottle rests. kThe filling heads areso constructed audarranged as to close the communication with the supply until a bottle is raised to make a sealed joint with the mouth of the filling head. and a rotar disc type of liquid inlet and an or, gas out et valve is used, the

said valve having one stationary membei and one rotary member each of whichis pfllCBd with leather, or other appropriate material, the air or gas outlet valve being fitted with manually operated adjusting f valve to "control the amount of air'or gas released from the bottles thusregulating the amount of liquid that can enter the bottles. In order that the said invention may be clearly understood and rcadilycarried into effect, the same is described more fully with :reference to the accompanying drawings, wherein:f+ r Q Fig. 1 is a vertical section partly inelelvation ota multiple headed rotary filler constructed in accordance withthis invention.

fig. 3 is ahorizontal section showingthe 1 cams which operate the bottle rests and also,

the,divisional bottleguards. p

Fig. 4 is a detail vertical section of a filler. head, drawn. to a larger scale.

Advertingto Fig. l the base casting 1 has a vertical bearing 2 through which a sleeve 3 extends and secured tosuch sleeve by a key 5 is awornl wheel 4 that is'driven by a worm 6 on a shaft 7 which is supported slidably mounte I the upperend of the. sleeve 3 is fixed a revolving table 9 by a key 10 and passing through the sleeve 3 is a vertical shaft 11 that is slidably keyed to the sleeve 3, by a key 12 so that when the sleeve 3 is'rotate'd the table 9 and shaft 11 are rotated also. On the top of shaft '11 is secured a top late or casting 13 by means of a key 14: an nut ,15 so that the casting 13 revolves with the shaft 11'.

Interposed between the sleeve 3: and casting 13 is a. spring 16 which supports the weight of the shaft 11 and is always tending to raise the casting 13 carrying the filling heads 17 and ilnaintain the latter at the greatest distance from the bottle rests 18 for taking the longest bottles. The shaft 11 is screwthreaded at its lower. end and on it is screwed abevel or other wheel 19 gearing with. a pinion 20 on a shaft 21 provided witha wheel 22 and supported in a bearing'23 fixed to the base 1. ;To lower the filling heads 17 the ,wheel 22. is revolved, thus turning the pinion 20 and bevel or other Wheel 19 which then acts as a nut to draw the shaft 11 downwards thereby compressing the springs 16 and lowering the'casting 13 and filling heads 17 to suitany required-lengthof bottle. The

wheel 19 normally revolves with theshaft (1'1, and revolves the shaft 21. and the, hand wheel22 idly. -On the base lismounted a stationarycam 24 for raisingand lowering "the bottle rests 18' in. a usualimanner .by

means of a roller 25 mounted on' a pin 26 in a slide 27 situated within a sleeve 28 con- 29, thesaid sleeve being in a supporting castin ,30 which is carried by the revolving tab e 9, the spring 29 allowing the sleeve 28 to move taming a spring which vary slightly in length. ,Oncan 24 is mounted a cam 31 which raises and lowers (rods 32 carrying a shoe 33 and a. divisional guard 34, the rod 32 sliding through a support 35 .fixedto the; revolving table 9. The guard 34 Fig. 3, is also, rotated through a small an 1e by thegshoe on-the mesa by means 0 7 side wings 31 and 31 on thecam by a machine such as described in the specification ofmy application for patent of even [down the slide 27 toaccommodate bottles, 1

date herewith or any similar machine. The

internal bottle guard is in two portions 36,

37 (Fig.1 1 the bottom portion 36 being fixed t the revolving table 9 and the. top portion 37 to the top casting 13. The top portion 37 when the top castingIS is lowereclfo'r fining small bottles. The pulley 38 -is slidable-on the shaft 7 to put the machine in or out of is moved by a rod39 caried by the base castingLl and operated by lever 40 (see Figs. 2' and=3) To'the base casting 1 are attached three pillars 41 carrying at'the top a ring42 bnr'vhich is mounted a liquid inlet supply 'valve-43 which is flexibly connected by aflex- 5 ible tube 44: to aliquid inlet distributing valve 45 'which has a port 46 for liquid,jof

-f0r gas, the latter being provided -w-itlra needle valve 48 for adjusting its area so as 20- to'control the'amount ofair'or gas pressure released from= thebottles. thus controlling the amountof fiuid entering the'bottles. The .1iquid inlet distribution valve 45 is held in a stationary-position by means of anarm 49 rib-50'cast-on such pillar. The liquid inlet distributionivalve 45 is' faced with a; renewable leather or ot-her seating 51 under which makesqa pressure tight joint witli'sameby '-means'of'a suitable'jointing washer 54. The distr ibution fitting '53 has alternate liquid ports 55 and air or' gas ports '56 -which as *the -di'stribution fitting revolvescome "under' a liquid port 46 I and Y a gas or air port 40 *valve' 45, thus in a knownnianner filling the bottles.- -Thestation aryiface 51 is -kept in pressure tight contact 1 with the revolving '-and-a lever which screws "on-toa rod 61 45 thatzis attached tothe'shaft 11,- one of the aawashers," 57 for example, a'dvantageou'sly be- 'inga spring :or flexiblev washer; The revolv- -"ingdistribution fitting 53 is rotated by'a peg 62 from the top of the shaft 1 1,"thus"rotating 50 *atthe same-speed'asthe fillingheads 17.
